Accessible via control system or Control Panel (menu point: cu.FA)!
Remark:
The UMC2 measures the currents of the lines in the bushing holes 冑 3 wiring and/or an external
current transformer result in a higher power line current.
If the Set current shall include the current factor to show e.g. the real rated motor current the cur-
rent factor must be changed before or together with the set current (3.2.3 and 3.2.4).
100 001.0
Current factor = 1  Current range 0.24-63 A (= default):
 Adjustment via control system: 1 or 100
Both values are identifi ed as current factor 1 = 100 %. If 1 or 100 has
to
be set, depends on the version of the confi guration fi le (.GSD, .EDS, ...)
 Adjustment via Control Panel: 001.0
173 001.7
Current factor = 1.73  Current range 0.4-109 A:
(needed for 冑3 circuits)
 Adjustment via control system: 173
Value 173 corresponds with current factor 1.73 = 173 %
 Adjustment via Control Panel: 001.7
Value 1.7 is internally corrected to 1.73 = 173 %
1000-64000
010.0-
640.0
Current factor = 10-640  Current range 50-3200 A:
(for circuits with external current transformers)
 Adjustment via control system: 1000 - 64000
Value 1000 corresponds to current factor 10 = 1000 %, ...
Value 64000 corresponds to current factor 640 = 64000 %, ...
 Adjustment via Control Panel: 010.0 - 640.0
2 ... 5
000.2
|
000.5
Current factor = 2-5  see section 3.2.5
 Adjustment via control system: 2 ... 5
The value shows, how many times the cable are looped through.
 Adjustment via Control Panel: 000.2 ... 000.5
